Answer:
17 degrees.
Step-by-step explanation:
In the problem, we are given that the lines are perpendicular meaning that those lines create 90 degree angles when they intersect. Since we know angles 1[3x+4] and 2[35], we can add those together and we get 3x+39. Finally, we set the 3x+39 equal to 90 degrees, and that gives us x=17 degrees.
